Microsoft (NASDAQ:MSFT) and Nokia (NYSE:NOK) have a problem -- each other.

The two companies came together under desperate circumstances in their 2011 deal. At the time, each company got something it badly needed. For Nokia, it came down to money. Microsoft was simply willing to shell out enough to buy Nokia time to transition away from its burning platform. For Microsoft, Nokia gave it an immediate flagship, brand-name partner from which it could launch into the smartphone space in order to compete with dominant rivals Apple and Google (NASDAQ:GOOGL). And while this deal seemed full of promise at the time, it hasn't quite been the home run both parties had hoped for. In this video, Fool contributor Andrew Tonner looks at the two companies and some interesting recent findings on which tech power needs the other more.
